Comparison: Is Sharp The Best Microwave (Updated | Dec 8th)

Consider how many people you regularly cook for and the size of dishes you use. A 0.9–1.1 cu. ft. model works well for singles or couples, while 1.6–2.2 cu. ft. units accommodate families and larger platters. Larger interiors also allow you to heat multiple items at once, reducing overall cooking time.

Higher wattage, such as 1200 W in the 2.2 cu. ft. model, heats food faster and provides more even results, especially for dense meals. Lower-wattage units (850–900 W) are adequate for reheating and simple meals but may need longer cook times. Choose wattage based on how quickly you want food prepared and the types of dishes you cook.

Sensor cooking automatically adjusts time and power for moisture‑rich foods, reducing guesswork and preventing over‑cooking. Auto‑cook presets let you start common items like popcorn or pizza with a single button. These conveniences add value for busy kitchens, especially in models with 10‑level power and 2‑stage cooking.

A removable turntable makes cleaning easier and allows you to use larger, rectangular dishes that wouldn’t fit on a fixed plate. Models with larger diameters (12.4–16.5 in.) give you more flexibility for big trays or casserole dishes. If you often cook bulky meals, a removable turntable is a practical feature.

The R‑21LCFS features a classic dial timer, a stainless steel exterior, and a spacious 1.0 cu. ft. interior designed for heavy‑use environments. It lacks modern sensor or LED displays but offers durability and easy maintenance for food‑service settings. Countertop models focus on sleek aesthetics, digital controls, and extra functions like inverter cooking.

Inverter technology provides continuous power levels, resulting in smoother heating and better texture for delicate foods like sauces or defrosted meat. It also reduces energy consumption compared to traditional on‑off cycling. If you value precise cooking and energy efficiency, the inverter‑enabled model offers a noticeable advantage.

Balance features you’ll actually use—such as sensor cooking, turntable size, and wattage—against price. Mid‑range models (around 1.0–1.4 cu. ft., 1000 W) often provide the best mix of capacity, digital controls, and presets without the premium cost of larger, high‑wattage units. For commercial or heavy‑use needs, the R‑21LCFS offers durability at a competitive price point.
